Well carry on if you like. Personally I don't understand how a platform line can be a "through platform" when there's a set of stops on it.

Think the only ones where the rails continue are Kirkby and Ormskirk. Otherwise, there's a fair few ex-through stations that now serve as terminii.
Theres one i cant remember the name of, it was the terminus of a Third Rail Line and the Terminus of a DMU line
Does Wimbledon count? There's a set of stops half way down one platform for the tram, but I don't know if the bit beyond the stops is used by trains. Probably not.

You mean p9/10. Should count: p9 is a bay for trains down to Tooting and the Sutton Loop (FCC) I think, and isn't in use too much, and p10 is now the Croydon Tramlink bay, it was heavy rail for West Croydon (now occupied by the tram), but saying all of this, I think it is physically blocked in the middle by something other than buffers, and was all along.
Platform 10 is used by the trams at the country end, and as a bay platform for heavy rail (although I can't recall ever having seen anything in it) at the London end.
Prior to Croydon Tramlink (or London Tramlink as its now called) platfornms 9 and 10 were both through lines, 9 being the up line and 10 being the down line. The West Croydon - Wimbledon trains usually used to terminate in platform 9 also.
Are you familiar with Fareham, Kirkby or Ormskirk station's? If so you will know what I mean. If not, imagine two through lines on a regular station with platforms but with one line now blocked by buffers thus preventing a through service (as is Fareham on one line only) Or in the case of Kirkby both through lines have back to back buffer stops preventing a train from making a through journey. However the through journey can proceed by walking from your DMU to the EMU a few yards down the platform past the buffers. phew!
I dont think Fareham really counts . If you removed the buffer stop you'd end up down the hole between the two A27 bridges , not on your way to Cosham .
Giving that platform over to the tram system probably seemed a great idea at the time, but I don't think it would happen nowadays. Running twice as many trains round the loop is a NR aspiration once Thameslink is in place, (ie 4 tph Blackfriars to London Bridge) but the present layout isn't too clever for that. It would require 8 calls an hour at Wimbledon, but timekeeping would need to be pretty exact because alternate trains would be in opposite directions.
Is there anywhere else practical to relocate the tram platform - outside the station would probably be a good idea if only to get rid of all those Oyster PAYG questions...
